about 6 Hz to as high as 5,000 Hz; tool acceleration levels can be very high (several hundred g's or more)
and these devices must be able to measure these high g levels; these devices must be rugged too. In all
cases care with the accelerometer cabling must be taken. It is certainly not advisable to drop any of
these devices on the ground or else they can be severely damaged and
or lose their calibration. Generally
the manufacturer will supply a calibration sheet with a newly purchased accelerometer. It is advisable to
